I just purchased a 2004 LS 430. When I tried to adjust the outside mirrors, I could adjust the left side mirror but not the right side (and, yes, I flipped the rocker arm to the right side). Later, neither mirror could be adjusted. I have been told that it would cost about $1200 to replace each mirror, but it seems to me that it could be a switch problem (hopefully, a cheap solution) rather than a motor problem in the mirrors themselves. I reach the conclusion based on the fact that the adjustment worked intermittently . . . but now is completely dead. Any ideas?
